[SURVPC] .JIF format (Was: .GIF correct pronunciation?)

[Marc D. Williams]

Heh, I just realized this was supposed to go to the list.
It'd be nice if the SurvPC headers included X-Mailing-List so I
don't have to always edit the To field when replying.
My mail reader can use that header if it exists.

That sounds familiar. Since I only have Linux at the moment I went
looking through graphics programs' man pages and a howto but couldn't
find the .JIF format.
However, .JFIF was mentioned in a few, only described as
`JFIF style jpeg images'

One man page describes JPEG as
  Joint Photographic Experts Group JFIF format; compressed 24-bit
  color.

I wonder, maybe .JIF is the DOS-compatible three-letter extension for JFIF
and JFIF was the original format/name before the JPEG people
decided on using their name as the extension instead (.jpeg/.jpg)??

One way to be sure about the format, if you ever come across a JIF again
download it and view it with a hex viewer/editor.
JPEG/JFIF files start with hex bytes `FF D8'.
If not then maybe it was a .GIF compatible file.
See what you did, now I'm interested in finding out. :-)

I just remembered an ad for a image development package called LEADTOOLS
and they list some 60 image formats but no .JIF.

Anyone know of a comprehensive reference on image file formats?
